MODE FOR CARRYING OUT THE INVENTION

Below, the preferred embodiment of the present invention is described with reference to the attached drawings.

A browsing system 1 according to the present invention is composed of a computer communication network 10 (hereafter called simply a communication network), a terminal 100, an image server 200, a document server 300 and a transformation server 400, as shown in FIG. 1.

The communication network 10 is composed, for example, of the Internet. The communication network 10 may also be a LAN (Local Area Network) or a public circuit network.

Before describing the terminal 100, the image server 200, the document server 300 and the transformation server 400 will be described.

The image server 200 stores multiple image IDs identifying images and image information represent those images, associating such with each other.

The document server 300 stores document information represents a document describing images stored on the image sever 200 and text explaining those images, and document path information expressing relative paths of that document information, associating such with each other. This document information includes information expressing text and image location information expressing the location of the images.

In this preferred embodiment, it is explained that the text expressed by text information stored by the document server 300 is Web pages written in HTML (HyperText Markup Language). However, this is intended to be illustrative and not limiting, for it would be fine for the document to be expressed in another markup language such as XML (eXtensible Markup Language), for example.

The transformation server 400 transforms documents (hereafter referred to as pre-transformation documents) by executing a prescribed transformation process on the text character strings of documents expressed by input document information, and outputs document information expressing the transformed document (hereafter referred to as post-transformation documents).

In this preferred embodiment, the prescribed transformation process executed by the transformation server is explained as a translation process, but this is intended to be illustrative and not limiting, for it would be fine for this to be a process that encrypts unencrypted documents, for example, or to be a process that deciphers encrypted documents.

The terminal 100 is described as comprising a personal computer, but it would be fine for this to comprise a PDA (Personal Digital Assistant) or a cell phone.

As shown in FIG. 2A, document location information expressing the location of the pre-transformation document which contains text character strings and an image MI to which characters or character strings are added (in other words expressed) is input into the terminal. In addition, a language specified by the user (hereafter referred to a “specified language”) and translation commands commanding translation of a document at a location expressed by the input document location information into the specified language are input into the terminal 100.

Next, the terminal 100 displays a post-translation document such as that shown in FIG. 2B which contains a text string that is the text string translated into the specified language, and an image MO expressing text or a text string that is the text or text string translated into the specified language.

In this preferred embodiment, the explanation assumes the language of the pre-transformation document (hereafter referred to as the pre-transformation language) is English and the specified language is Japanese, but this is intended to be illustrative and not limiting.

As shown in FIG. 3A, the terminal 100 comprises a CPU (Central Processing Unit) 100 a, a ROM (Read Only Memory) 100 b, a RAM (Random Access Memory) 100 c, a hard disk 100 d, a media controller 100 e, a LAN (Local Area Network) card 100 f, a video card 100 g, an LCD (Liquid Crystal Display) 100 h, a keyboard 100 i, a speaker 100 j and a touch pad 100 k.

The CPU 100 a accomplishes complete control of the terminal 100 by executing software processes in accordance with programs stored on the ROM 100 b or the hard disk 100 d. The RAM 100 c temporarily stores data that is to be processed during execution of a program by the CPU 100 a.

The hard disk 100 d stores tables preserving various kinds of data. The terminal 100 may also be provided with flash memory in place of the hard disk 100 d.

The media controller 100 e reads various types of data and programs from recording media including flash memory, CD (Compact Disc), DVD (Digital Versatile Disc), or Blu-ray Disc (registered trademark).

The LAN card 100 f sends and receives data among the image server 200, the document server 300 and the transformation server 400, connected via the communication network 10.

The keyboard 100 i and the touchpad 100 k input signals or information in accordance with operation by the user. The terminal 100 may be provided with a touch panel in place of the touchpad 100 k.

The video card 100 g draws (that is to say, renders) images based on digital signals output from the CPU 100 a, and also outputs image signals indicating the drawn image.

The LCD 100 h displays images in accordance with image signals output from the video card 100 g. The terminal 100 may be provided with a PDP (Plasma Display Panel) or an EL (Electroluminescence) display in place of the LCD 100 h.

The speaker 100 j outputs audio based on signals output from the CPU 100 a.

The configurations of the image server 200, the document server 300 and the transformation server 400 are the same as the configuration of the terminal 100, so explanation of such is omitted.

The CPU 100 a of the terminal 100 executes a script process specified by the below-described post-transformation document based on the post-transformation document display process of FIG. 4A. Through this, the CPU 100 a functions as an image location information extraction part 150, an additional information extraction part 151, an image location information generation part 152 and a overwriting part 153, as shown in FIG. 5A.

In addition, the CPU 100 a works together with the LAN card 100 f of FIG. 3 to function as a document request transmission part 120, a document response receiving part 130, an image request transmission part 160 and an image response receiving part 170. Furthermore, the CPU 100 a works together with the keyboard 100 i and the touchpad 100 k to function as a document location information accepting part 110, and works together with the LCD 100 h to function as a document display part 180.

An unrepresented CPU of the transformation server 400 functions as a document location information extraction part 420 and a transformation part 450 such as that shown in FIG. 5B by executing the transformation process shown in FIG. 4B. In addition, the CPU of the transformation server 400 works together with a unrepresented LAN card to function as a document request receiving part 410, a document request transmission part 430, a document response receiving part 440 and a document response transmission part 460.

An unrepresented CPU of the document server 300 functions as a document retrieving part 330 such as is shown in FIG. 5C by executing the document transmission process of FIG. 4C. In addition, the CPU of the document server 300 work together with an unrepresented hard disk to function as a document storage 310, and works together with an unrepresented LAN card to function as a document request receiving part 320 and a document response transmission part 240. The document storage 310 stores multiple items of the above-described document path information and document information associated with each other.

An unrepresented CPU of the image server 200 functions as an image retrieving part 230 and an image generation part 240 such as those shown in FIG. 5D by executing the image transmission process of FIG. 4D. In addition, the CPU of the image server 200 works together with an unrepresented LAN card to function as an image request receiving part 220 and an image response transmission part 250, and works together with an unrepresented hard disk to function as an image storage 210. The image storage 210 stores multiple of the above-described images ID and image information associated with each other.

Below, the post-transformation document display process for displaying a post-transformation document shown in FIG. 2B is described with reference to FIG. 4A.

The CPU 100 a of the terminal 100 starts the post-transformation document display process of FIG. 4A when a signal is input from the keyboard 100 i or the touchpad 100 k or FIG. 3.

When the post-transformation document display process is started, the URL of the transformation sever 400 input by the user and a URL indicating the location of the document to be transformed by the transformation server are input into the document location information accepting part 100 of FIG. 5A.

Here, an explanation will be given assuming that “http://www.transformserver.co.jp” is input as the URL of the transformation server 400.

In addition, the explanation will be given assuming that “http://www.documentserver.co.jp/dir/page.html” is input as the URL indicating the location of the document to be transformed by the transformation server 400.

Next, the document location information accepting part 110 accepts the first document location information “http://www.transformserver.co.jp?first_parameter” based on the input URL. Here, the first document location information is information specifying a first parameter designating the below-described second document location information with the transformation server 400 as the destination of the request. That is to say, within the first document location information, the part “transformserver.co.jp” indicating the domain name (it would be fine of this were the IP address) of the server contained in the URL of the transformation server 400 is the part that makes that server the transmission destination (that is to say, the request destination) of the request. In addition, to designate the first parameter through the first document location information, the method of adding that first parameter after adding the character “?” to the end of that part is used.

In addition, the second document location information is information specifying a second parameter designating a pre-transformation document, with the document server 300 as the request destination. This second document location information is the above-described URL accepted, namely “http://www.documentserver.co.jp/dir/page.html”. In other words, “documentserver.co.jp” in the URL is the part identifying the document server 300 as the transmission destination, and the part “dir/page.html” indicating the relative path of the pre-transformation document on the document server 300 is the second parameter designating this pre-transformation document.

In addition, the document location information accepting part 100 accepts, besides the first document location information, information indicating the pre-transformation language, information indicating the specified language specified by the user and a translation command commanding the document in the pre-transformation language to be translated into the specified language (step S11).

Following this, the document location information accepting part 110 generates a parameter “sl=en&tl=ja” indicating that the pre-transformation language is English and the specified language is Japanese. Following this, the document location information accepting part 110 further adds the parameter “s=en&tl=ja” to the first parameter “u=http://www.documentserver.co.jp/dir/page.html” designating the second document location information. Through this, the document location information accepting part 110 sets “http://www.transformserver.co.jp?sl=en&tl=ja&u=http://www.documentserver.co.jp/dir/page.html” as the first document location information.

Next, the document request transmission part 120 of FIG. 5A generates a first document request (hereafter called the “first request”) based on the first document location information, and transmits the generated first document request to the transformation server 400 (step S12). The first request is a request seeking for the first request transmission part 120 to transmit document information indicating the post-transformation document as a first document response (hereafter called the “first response”), and is a request specified by the above-described first parameter. Here, the explanation of the post-transformation document display process executed by the terminal 100 will be temporarily interrupted.

An unrepresented CPU of the transformation server 400 starts the transformation process shown in FIG. 4B when an unrepresented LAN card receives data.

When the transformation process starts, the document request receiving part 410 of FIG. 5B receives the first document request (in other words, the first request) from the terminal 100 (step S21).

Next, the document location information extraction part 420 extracts the first parameter “sl=en&tl=ja&u=http://www.documentserver.co.jp/dir/page.html” from the first document request. Furthermore, the document location information extraction part 420 extracts the second document location information “http://www.documentserver.co.jp/dir/page.html” from the extracted first parameter, and extracts the information “sl=en” indicating the pre-transformation language and the information “tl=ja” as the specified language (step S22).

Following this, the document request transmission part 430 transmits a second document request (hereafter also called the “second request”) specifying the second parameter “dir/page.html” to the document server 300 specified as the request destination in the extracted second document location information (step S23). Here, the explanation of the transformation process executed by the transformation server 400 will be temporarily interrupted.

An unrepresented CPU of the document server 300 starts the document transmission process shown in FIG. 4C when an unrepresented LAN card receives data.

When the document transmission process is started, the document request receiving part 320 of FIG. 5C receives the second document request (in other words, the second request) from the transformation server 400 (step S31).

Next, the document retrieving part 330 generates document path information for the document whose transmission is requested, from the second parameter “dir/page.html” specified in the received second document request, and retrieves document information stored in the document storage 310 corresponding to the generated document path information (step S32).

Next, the document response transmission part 340 replies to the transformation server 400 with the retrieved document as the second response (in other words, the document response) (step S33), and then execution of the document transmission process concludes.

Next, the explanation of the transformation process executed by the transformation server 400 is restarted.

Following step S23 in FIG. 4B, the document response receiving part 440 of FIG. 5B receives document information as the second document response (that is to say, the second response) from the document server 300 (step S24).

Next, the transformation part 450 accomplishes a text transformation process that translates the text character strings of the transform document indicated by the received document information from the pre-transformation language of English indicated by the information “sl=en” extracted in step S22 into the specified language of Japanese indicated by the information “tl=ja” (step S25).

Following this, the document response transmission part 460 of FIG. 5B transmits document information indicating the post-transformation document as the first document response (that is to say, as the first response) to the terminal 100 (step S26), and following this, execution of the transformation process concludes.

In this preferred embodiment, the pre-transformation document is a document written in HTML, such as that shown in FIG. 6A. This document contains English character strings such as “Sale” and “Price $4.95” in the area surrounded by the “body” tag BDI. In addition, when this document can carry an image at a location indicated by the image location information “./img.gif” contained in the “src” attribute of the “img” tag IMI, that image is carried between the above-described character strings “Sale” and “Price $4.95”. In contrast, when this document cannot carry that image, the character string “Lady's Outlet” described at the “alt” attribute is carried.

In addition, in this preferred embodiment, the character string “Lady's Outlet” described in the “alt” attribute is used as a character string added to that image (that is to say, is indicated as an image in that image), so the information indicating the character string described in the “alt” attribute is labeled as additional information.

The transformation server 400 translates the document information of FIG. 6A into the document information of FIG. 6B in step S25 of the above-described FIG. 4B. At this time, the transformation server 400 translates the English character strings “Sale” and “Price $4.95” and/or the like into the Japanese “

” and “

” 4.95 “

” and/or the like. In addition, the transformation server 400 translates the character string “Lady's Outlet” described in the “alt” attribute of the “img” tag IMI shown in FIG. 6A into the Japanese “

”, and through this transforms the “img” tag IMI into “img” tag IMO.

However, the transformation server 400 does not translate the control code used in executing the program, such as the image location information “./img.gif” described in the “src” attribute of the “img” tag IMI or other tags. This is so that the program's execution process is possible and execution of the control content executed does not change even if messages or sentences input and output before and after translation change.

In addition, in the pre-transformation document, the function name “transText( )” is described in the “onload” attribute of the “body” tag BDI, as shown in FIG. 6A. A function FCI of this function name accomplishes an image location information change process changing the image location information carried in the “img” tag indicated by the document information of the process target, with the document information of that function's call as the process target. Details of the image location information change process are described below.

This image location information change process is determined by a character string described in a computer language such as JavaScript (registered trademark). The transformation server 400 for example excludes character strings contained in comments and quotation marks, and does not accomplish a transform of character strings indicating this image location information change process. That is because processes executed before and after translation are not changed (in other words, programs are maintained).

The image location information change process executed by the function FCI may be described in the HTML file that is the function FCI's call, or may be described in a file differing from the HTML file, such as a js file.

Next, the explanation of the post-transformation document display process executed by the terminal 100 will be restarted.

Following step S12 in FIG. 4A, the document response receiving part 130 of FIG. 5A receives the first response from the transformation server 400 (step S13).

Next, when browsing of the document information of the post-transformation document received as the first response concludes, a load process is executed that starts execution of the function FCI described in the “onload” attribute of the “body” tag BDI (step S14)

When execution of the above-described function FCI begins, the image location information change process shown in FIG. 7 is executed with the document information of the post-transformation document as the process target (step S15).

When the image location information change process of FIG. 7 is started, the image location information extraction part 150 of FIG. 5A acquires the return value obtained by giving the character string “testImg*” as an argument to a method known as “getElementByIdQ”. Through this, the image location information extraction part 150 extracts the “img” tag (hereafter called the target img tag) IMO having the “id” attribute of “testImg” from the document information that was the process target, such as is shown in FIG. 6B (step S51).

Next, the image location information extraction part 150 references the “src” property of the instance of the target img tag IMO acquired as a return value. Through this, the image location information extraction part 150 extracts the image location information “./img.gif? described in the “src” attribute of the target img tag IMO from that tag IMO (step S52).

Following this, the additional information extraction part 151 similarly extracts additional information specifying the character string “

” described in the “alt” attribute from the extracted target img tag IMO, and accomplishes an additional information extraction process stored in the variable “text” (step S53).

Following this, the image location information generation part 152 executes an image location information generation process that generates new image location information (also called image obtaining information) based on the image location information extracted by the additional information extraction part 151 and the additional information stored in the variable “text” (step S54).

With this preferred embodiment, the explanation assumes that the new image location information of ‘http://www.imageserver/imgtest.php?bkimg=bk1.jpg&setstring=

” is generated. This new image location information contains the part “http://www.imageserver” specifying the image server 200 as the request destination. In addition, this new image location information contains the part “imgtest.php?bkimg=bk1.jpg&setstring=” specifying the image parameter designating additional information specifying the character string “

” or the characters added to the background information and background image identifying the background image. Furthermore, this new image location information contains additional information specifying “

” stored in the variable “text”.

Next, the overwriting part 153 overwrites the “src” property of the instance of the target img tag IMO to the generated new image location information. Through this, the transformer sets this new image location information to the “src” attribute of the “img” tag IMO (step S55) and then execution of the image location information change process concludes.

Following step S15 in FIG. 4A, the image request transmission part 160 of FIG. 5A generates an image request (hereafter also called an image transmission request) specifying the above-described image parameter ‘http://www.imageserver/imgtest.php?bkimg=bk1.jpg&setstring=“

”’ based on the overwritten new image location information. Next, the image request transmission part 160 transmits the generated image transmission request to the image server 200 (step S16). Here, explanation of the post-transformation document display process executed by the terminal 100 will again be interrupted.

An unrepresented CPU of the image server 200 starts an image transmission process like that shown in FIG. 4D when data is received by an unrepresented LAN card.

When the image transmission process is started, the image request receiving part 220 of FIG. 5D receives the image request (that is to say, the image transmission request) from the terminal 100 (step S41).

Next, the image retrieving part 230 extracts the image parameter “imgtest.php?bkimg=bk1.jpg&setstring=

” from the image request. Next, the image retrieving part 230 retrieves image information of the background image attached corresponding to the same image ID as the background information “bk1.jpg” designated by the extracted image parameter, from the image storage 210 (step S42).

Next, the image generation part 240 reads the retrieved image information from the image storage 210 (step S43).

Following this, the image generation part 240 designates the additional information based on the extracted image parameter “imgtest.php?bkimg=bk1.jpg&setstring=

”. Next, the image generation part 240 generates character images indicating the post-translation character string “

” specified by the additional information. Following this, an image MO to which the generated character image is added (in other words, overlaid) is generated for the background image indicated by the read image information (step S44).

Following this, the image response transmission part 250 of FIG. 5D transmits image information indicating the generated image MO to the terminal 100 as the image response (hereafter also called image response) (step S45), and following this execution of the image transmission process concludes.

Next, explanation of the post-transformation document display process executed by the terminal 100 will be restarted.

Following step S16 in FIG. 4A, the image response receiving part 170 of FIG. 5A receives the image response (that is to say, the image response) from the image server 200 (step S17).

Next, the document display part 180 displays the image MO indicated by the image information received as an image response and a text character string indicated by the document information of the post-transformation document on the screen FO, as shown in FIG. 2B (step S18), and following this execution of the post-transformation document display process concludes.

Next, a pre-transformation document display process for displaying the pre-transformation document shown in FIG. 2A is explained with reference to FIG. 8A in order to compare to the post-transformation document display process explained with reference to FIG. 4A.

When the pre-transformation document display process is started in the terminal 100, the document location information accepting part 110 of FIG. 5A accepts as second document location information the URL “http://www.documentserver.co.jp/dir/page.html” indicating the location of a pre-transformation document input by the user (step S61).

Next, the document request transmission part 120 of FIG. 5A transmits the second document request (that is to say, the second request) specifying the second parameter “dir/page.html” of the second document location information to the document server 300 (step S62).

When an unrepresented LAN card receives the data, the document server 300 starts a document transmission process like that shown in FIG. 8B, similar to above. When the document transmission process is started, the document server 300 executes the same process as in steps S31 to S33 of FIG. 4C and then execution of the document transmission process concludes.

In other words, the document server 300 receives the second document request (that is to say, the second request) from the terminal 100 (step S81) and retrieves document information such as that shown in FIG. 6A based on the second document request received (step S82). Following this, the document server 300 replies with the retrieved document information to the terminal 100 as the second response (that is to say, the second document response) (step S83).

Following step S62 in FIG. 8A, the document response receiving part 130 of the terminal 100 shown in FIG. 5A receives the second response from the document server 300 (step S63). Following this, when browsing of the document information of the pre-transformation document received as the second response is concluded, a load process is executed that starts execution of the function FCI described in the “onload” attribute possessed by the “body” tag DBI of FIG. 6A (step S64).

When execution of the above-described function FCI is started, the image location information change process of FIG. 7 is executed with the document information of the untransformed document as the process target (step S65). Through executing this process, the “img” tag IMI is extracted from the document information of the pre-transformation document shown in FIG. 6A, and the additional information specifying the untransformed character string “Lady's Outlet” described in the “alt” attribute possessed by the “img” tag IMI is extracted. Following this, new image location information (that is to say, image import information) composed of image parameters designating that additional information, “http://www.imageserver/imgtest.php?bkimg=bk1.jpg&setstring=Lady's Outlet”, is generated. Following this, the new image location information is set to the “src” attribute possessed by the “img” tag IMI of FIG. 6A.

Following step S65 in FIG. 8A, a process similar to step S16 through step S18 of FIG. 4A is executed (steps S66 through S68), and then execution of the pre-transformation document display process concludes. Through this, the text character strings “Sale” and “$4.95” that are not transformed as shown in FIG. 2B, and the image to which the untransformed character string “Lady's Outlet” was added, are displayed on a screen FI of FIG. 2A.

According to these configurations, the terminal 100 extracts additional information from the post-transformation document (hereafter called the first document) whose test character strings were transformed, and displays the image to which the characters or character strings specified by the extracted additional information was added, and the transformed text character string of that post-transformation document (that is to say, the first document). Consequently, the terminal 100 can display a post-transformation document containing an image indicating the transformed characters or character strings and the transformed text. In other words, the user can peruse the post-transformation document (first document) containing an image indicating the transformed characters or character strings and not just the transformed text.

In addition, according to these configurations, the terminal 100 accepts second document location information specifying a second parameter designating the pre-transformation document (hereafter called the second document) on which the transformation process has not been conducted. Upon accepting the second document location information, the terminal 100 extracts the additional information from the pre-transformation document, and displays the image to which the characters or character strings specified by the extracted additional information are added, and the text character string of the pre-transformation document. Consequently, the terminal 100 can display the pre-transformation document containing the image indicating the untransformed characters or character strings, and untransformed text. In other words, the user can peruse the pre-transformation document (that is to say the second document) containing not just the untransformed text but also an image indicating the untransformed characters or character strings.

Thus, as has already been explained, because the characters and character strings described in the “src” attribute of the “img” tag written in HTML indicate the location of the image displayed, normally such is excluded from being an object of the transformation process. In contrast, the characters and character strings described in the “alt” attribute of the “img” tag are displayed in place of that image when an image has not been acquired or cannot be acquired from the location described in the “src” attribute, and thus normally becomes a target of the transformation process. In addition, the terminal 100 executes the program in which the “onload” attribute of the “body” tag is described before acquiring an image from the location described in the “src” attribute of the “img” tag. Hence, according to these configurations, the terminal 100 executes the program in which the “onload” attribute is described before acquiring the image at the location described in the “src” attribute of the “img” tag. Consequently, if the terminal 100 receives the post-change document (the first document) that is a transformation of the pre-transformation document (second document) expressed in HTML, the terminal can receive the image that is at the location described in the “src” attribute of the “img” tag that did not become the target of transformation and to which are added characters or character strings indicating the “alt” attribute of the “img” tag that was a target of transformation.

In addition, according to these configurations, after extracting the additional information from the translated text character strings of the pre-transformation document (second document), the terminal 100 displays the image to which the characters or character strings specified by the extracted additional information are added, and the translated text character strings of the pre-transformation document (second document). Consequently, the terminal 100 can display the document containing the image indicating the translated characters or character strings and the translated text, even without storing in advance images to which characters or character strings translated into each translation language have been added. In addition, when the image contained in the pre-transformation document is an advertising image and the characters or character strings added to that image express advertising content, the characters or character strings expressed in the image are also displayed translated and not just the text character strings carried in the document so it is possible to advertise to users with a stronger appeal than in the past.

(First Variation)

With this preferred embodiment, the browsing system 1 was explained as comprising the separate devices of a terminal 100, an image server 200, a document server 300 and a transformation server 400. However, this is intended to be illustrative and not limiting, for two or more out of the terminal 100, the image server 200, the document server 300 and the transformation server 400 may be integrally composed. For example, the image server 200 and the document server 300 may be integrally composed, or the terminal 100, the image server 200, the document server 300 and the transformation server 400 may all be integrally composed.

(Second Variation)

Furthermore, the terminal 100, the image server 200, the document server 300 and the transformation server 400 may each be realized with multiple devices. In other words, the functions the terminal possesses may be realized with multiple devices. Similarly, the functions the image server 200, the document server 300 and the transformation server 400 respectively possess may be respectively realized with multiple devices.

(Third Variation)

In addition, in this preferred embodiment the additional information was explained as specifying the characters or character strings described in the “src” attribute of the “img” tag. In addition, the additional information extraction part 151 of FIG. 5A was explained in step S53 of FIG. 7 as extracting the characters or character strings described in the “alt” attribute of the “img” tag extracted from the document using the method of “getElementByIdQ”. However, this is intended to be illustrative and not limiting, for it would be fine for example for the additional information to be characters or character strings enclosed by a different type of tag having the “class” attribute or the “id” attribute in which character strings (for example, the same character strings or partially the same character strings) corresponding to the character string “testImg” described in the “id” attribute of the “img” tag. In particular, the characters or character strings enclosed by those other types of tags may be set so as to not be visible. The characters or character strings enclosed by that kind of different type of tag or that tag can be extracted from the document using the method of “getElementsByClassName( )” that returns elements of tags having the “class” attribute of a prescribed name.

According to these configurations, if this is a tag possessing the “id” attribute or the “class” attribute, the tag is used as a tag enclosing the characters or character strings added to the image, so it is possible to note more freely than in the past the characters or character strings added to the image for the document.

(Fourth Variation)

Furthermore, the additional information may be characters or character strings enclosed by “”” (parentheses) in JavaScript (registered trademark). According to this configuration, the characters or character strings added to the image can be described more freely than in the past.

(Fifth Variation)

In addition, in this preferred embodiment the image location information extraction part 150 was explained as extracting the elements of the “img” tag possessing the “id” attribute described be a prescribed character string “testImg” for example using the method “getElementsByIdQ”. Furthermore, the image location information extraction part 150 was explained as being able to extract the elements of the tag possessing the “class” attribute described by the prescribed character string “testImg” for example using the method “getElementsByClassName( )”. However, this is intended to be illustrative and not limiting, for the image location information extraction part 150 can acquire elements of the tags even for “img” tags not possessing the “id” attribute or the “class” attribute or in which the “id” attribute or the “class” attribute are not described, using “getElementsByTagName( )”. The tag for which the elements are acquired is not limited to the “img” tag and may be a different type of tag. According to this configuration, when elements of the “img” tag contained in an HTML document are successively extracted and the image location information change process of FIG. 7 is applied to each of these it is not necessary to specify in advance the “id” attribute or the “class” attribute in the “img” tag.

(Sixth Variation)

The background information may be information identifying the image at a location expressed by the image location information “./img.gif” extracted from the post-transformation document or the pre-transformation document by the additional information extraction part 151. In addition, the background information may be described in advance in a program such as JavaScript (registered trademark) specified by the pre-transformation document (that is to say, a program also specified by the post-transformation document).

According to these configurations, the terminal 100 displays an image to which transformed characters or character strings are added to the background image identified by background information described in the program specified by the pre-transformation document or the pre-transformation document (second document). Consequently, if the background information described in the program specified by the pre-transformation document or the pre-transformation document (second document) is caused to vary, the terminal 100 can display the post-transformation document (first document) containing an image to which the post-transformation characters or character strings are added to a different background.

(Seventh Variation)

Furthermore, in this preferred embodiment, the terminal 100 was explained as extracting elements of one “img” tag in which the character string of “testImg” is described, from document information indicating the document. In addition, the terminal 100 was explained as displaying a document containing an image in which a character string described in the “alt” attribute possessed by the “img” tag whose elements were extracted is added a background image at a location indicated by image location information described in the “src” attribute possessed by the “img” tag. However, this is intended to be illustrative and not limiting, for the terminal 100 can extract elements of the “img” tag (hereafter called the first “img” tag) described in the “id” attribute by the character string “testImg1”, elements of the “img” tag (hereafter called the second “img” tag) described in the “id” attribute by the character string “testImg2”, and elements of the “img” tag (hereafter called the third “img” tag) described in the “id” attribute by the character string “testImg3”, from document information indicating the document. With this configuration, the terminal 100 can display a document containing an image in which the character string of the “alt” attribute of the first “img” tag is added to the background image designated by the “src” attribute of the first “img” tag, an image in which the character string of the “alt” attribute of the second “img” tag is added to the background image designated by the “src” attribute of the second “img” tag, and an image in which the character string of the “alt” attribute of the third “img” tag is added to the background image designated by the “src” attribute of the third “img” tag.

(Eighth Variation)

Furthermore, this preferred embodiment was explained with the image parameter designating the additional information and the background information and the image server generating an image in which characters or character strings expressed by additional information are added to a background image identified by the background information designated by the image parameter. However, this is intended to be illustrative and not limiting, for it would be fine for the image parameter to designate, besides the additional information and the background information, style information indicating a style or styles for adding characters or character strings expressed by that additional information to the image. In addition, it would be fine for the image server to add those characters or character strings to the image with a style or styles indicated by the style information designated by the image parameter. In particular, a style or styles for adding the characters or character strings to the image include one or more out of the font, font size, font color, thickness, presence of border and absence or presence of border of the characters or character strings. According to these configurations, the image parameter designates the additional information, the background information and the style information, so it is possible to match the style or styles of the characters or character strings added to the background image with the style or styles of background image. In particular, when the background image is an advertisement image, the style or styles of the characters or character strings added to the background image can be a style or styles, such as a style or styles matched to the style or styles of background image or differs from the style or styles from the style or styles of background image, that is/are easy for the user to confirm by sight to increase the appeal of advertisements more than in the past.

The preferred embodiment and the above-described multiple variations can be mutually combined. Naturally, it is possible to supply a terminal 100 provided in advance with configurations for realizing the functions according to the preferred embodiment, and by applying a program, it is also possible to cause an existing terminal to function as the terminal 100 according to the preferred embodiment. In other words, it is possible to cause an existing terminal to function as the terminal 100 according to the preferred embodiment by applying a program for causing the various functional components of the terminal 100 illustrated in the above-described preferred embodiment to be realized so as to be executable by a computer (CPU and/or the like) controlling the existing terminal.

Similarly, it is naturally possible to provide a configuration for realizing the functions according to the preferred embodiment as the image server 200 prepared in advance, and it is also possible to cause an existing image sever to function as the image server 200 according to the preferred embodiment by applying a program. In other words, it is possible to cause an existing image server to function as the image server 200 according to the preferred embodiment by applying a program for casing the various function components of the image server 200 illustrated by the above-described preferred embodiment so as to be executable by a computer (CPU and/or the like) controlling the existing image server.

The method of distributing this kind of program is arbitrary, and for example distribution is possible by storing such on a recording medium such as a memory card, a CD-ROM, a DVD-ROM and/or the like, and distribution is also possible via a communication medium such as the Internet and/or the like. In addition, the browsing method according to the present invention can be implementing using the browsing system 1 according to the present invention.

Having described and illustrated the principles of this application by reference to one preferred embodiment, it should be apparent that the preferred embodiment may be modified in arrangement and detail without departing from the principles disclosed herein and that it is intended that the application be construed as including all such modifications and variations insofar as they come within the spirit and scope of the subject matter disclosed herein.
